Xiao Chen created HADOOP-13155: ---------------------------------- Summary: Implement TokenRenewer in KMS and HttpFS Key: HADOOP-13155 URL: https://issues.apache.org/jira/browse/HADOOP-13155 Project: Hadoop Common Issue Type: Bug Reporter: Xiao Chen Assignee: Xiao Chen
DelegationToken is done in Yarn by {{DelegationTokenRenewer}}, where it calls {{Token#renew}} and uses ServiceLoader to get the renewer class ([code|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/token/Token.java#L382]) We seem to miss the token renewer class in KMS/HttpFSFileSystem, and hence Yarn defaults to {{TrivialRenewer}} for DT of these kinds, resulting in the token not renewed. As a side note, {{HttpFSFileSystem}} does have a {{renewDelegationToken}} API, but I don't see it invoked in hadoop code base. KMS does not have any renew hook. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
